i7 920: will that be enough?
Ok Here are my Scores when I had my old processor the Pentium D 940. With a ATI HD5850
See the problem my GPU score should be much higher but the processor is holding it back.
Also you must uninstall all Your PhysX software and reinstall with the ATI. This will fix most of your problems.
I will post my scores with the Intel Q9400 in the same rig tomorrow.
